Heat transfer coefficient of aluminum is much better in Aluminum.

coeff. (k=Wm-1K-1)

carbon steel = 50
stainless steel = 25
aluminium = 237

 

Copper or Gold would be better. I agree Aluminum would be best to work with.

 

It's pretty straightforward. Just insert the filter in the main vacuum line in the PCV circuit. It's usually a port somewhere on the intake manifold. With a pressurized intake such as ours, it may be routed differently or possibly have a check valve. Since I'm just learning this engine, I'll defer to people with service data and more experience.

 

A material that more readily transfers heat from the surrounding hot air may not be the most desireable for intake plumbing. A lower thermal mass is usually good, as it will recover quicker from heating. Generally plastics work pretty well in these applications, because they neither store nor transfer heat particularly well. My measurements using thermistors in the intake tract show insulation around the plumbing to be quite effective regardless of the underlying material.
